“Pirates of the Caribbean: The Curse of the Black Pearl” was a delightful left field surprise: a funny, rollicking, swashbuckling adventure (as well as the greatest film ever based on an amusement park ride). So what does director Gore Verbinski do for an encore? According to critics, more, more, more. And that’s not necessarily a good thing. In “Dead Man’s Chest,” Johnny Depp is back as the scoundrel Jack Sparrow, with Keira Knightley and Orlando Bloom along for the ride, this time aboard a craft containing the cephalopodan Davy Jones and his crew. The scribes say that while there are plenty of interesting effects and exciting set pieces, there’s just too much in this “Chest,” and it lacks the easygoing, organic charm of the original. At 55 percent on the Tomatometer, this “Pirates'” life may or may not be for you. And it’s well below the high watermark set by the original (at 79 percent).

“Dead Man’s Chest”: Rated ARRRGH!

The writings of Philip K. Dick have inspired a bunch of good-to-great movies (“Blade Runner,” “Total Recall,” “Minority Report“) and it’s easy to see why: Dick spun futuristic, Orwellian sci-fi tales that are chock full of paranoia and multilayered plot points. With “A Scanner Darkly,” Richard Linklater adapts Dick’s novel with the rotoscoping techniques he applied to “Waking Life.” The story involves a cop (Keanu Reeves) who is so far undercover in a drug investigation that it’s unclear he’ll ever find his way out. The critics say this one’s a visually arresting head trip, but some say it’s not quite as compelling as it wants to be. At 63 percent on the Tomatometer, this one may be worth a “Scan.”
